Strawberry GraphQL @ 0.278.0

Released

Add GraphQL Query batching support

GraphQL query batching is now supported across all frameworks (sync and async) To enable query batching, add a valid batching_config to the schema configuration.

This makes your GraphQL API compatible with batching features supported by various client side libraries, such as Apollo GraphQL and Relay .

Example (FastAPI): 

import strawberry
 
from fastapi import FastAPI
from strawberry.fastapi import GraphQLRouter
from strawberry.schema.config import StrawberryConfig
 
 
@strawberry.type
class Query:
    @strawberry.field
    def hello(self) -> str:
        return "Hello World"
 
 
schema = strawberry.Schema(
    Query, config=StrawberryConfig(batching_config={"max_operations": 10})
)
 
graphql_app = GraphQLRouter(schema)
 
app = FastAPI()
app.include_router(graphql_app, prefix="/graphql")

Example (Flask): 

import strawberry
 
from flask import Flask
from strawberry.flask.views import GraphQLView
 
app = Flask(__name__)
 
 
@strawberry.type
class Query:
    @strawberry.field
    def hello(self) -> str:
        return "Hello World"
 
 
schema = strawberry.Schema(
    Query, config=StrawberryConfig(batching_config={"max_operations": 10})
)
 
app.add_url_rule(
    "/graphql/batch",
    view_func=GraphQLView.as_view("graphql_view", schema=schema),
)
 
if __name__ == "__main__":
    app.run()

Note: Query Batching is not supported for multipart subscriptions
